REAL TIME OBSERVATIONS GMT OBSID ----------------------------------------------------------------- 3 fids, 5 stars 1516 2831 Notes from 9 am meeting ------------------------ OPS: Passes 2 over the last day(s) Dumps current Data loss We may have lost the Start Science part of the asteroid observation. We are pursuing this issue. Load is good -> 349/1500 CAPs 648P: Dec. ephemeris update Next passes 1510, 2330 MP: DEC17 is awaiting flt. dir. approval. DEC24 products will be out toward the end of the week. This will be a two week load. We have the OR list for JAN07; work will start this week. S/C: EPHIN temperature is still high. GOT: OFLS was down, is back up now. DATA: There is a problem processing OBSID 593, because a dropout occurred just at the time of Start Science. We are looking into ways of tricking the data processing system into processing this observation. SOT: Proton rates are elevated and rising slowly, but well below thresholds. Solar flare activity was high yesterday. There were an M and an X class flares yesterday at 0808 UT. There was a partial CME. There is a low chance of a CME arriving within 96 hrs and a high chance of M or X class flares in the next 48 hours. MEETINGS: -------- Data ---- On colossus (/dsops/GOT/input), - Dec 12 05:34 2001_345_2145_346_0621_Dump_EM_22931.gz Evaluation of QL data --------------------- Target: OBSID SI SOT Eval. ---------------- -- --------- NOTES/ISSUES/PROBLEMS --------------------- We may have lost an entire asteroid observation (OBSID 593) because the small interval containing the Start Science was lost. The processing system depends on having that Start Science to operate properly. It would be useful to see if there is a flag in the ACIS telemetry that continuously indicates the presence of a science run.
